Initial designs show a glass-curtained tube with cutaways spiraling up and around the facade to reveal segments of terraced verdure, like cultivated patches on the side of a steep alpine slope. "We didn't just fill up the tower," the architect says. "We've taken space away [from the apartments] to create the gardens," which are actually balconies tucked within the envelope. "It's as if nature has come back into the city," he says.

The Metropolitan Life Tower is located on the east side of Madison Square Park at 1 Madison Avenue. It has quietly become one of my favorite buildings in the city; I find myself peering up at it whenever I'm in the area. (I took a photo of the building while in line at the Shake Shack last spring...it's a lovely color in the late afternoon light.) Inspired by a photo posted recently to Shorpy that shows the tower under construction -- and before the addition of the building's iconic clock -- I did some research and discovered three things.

Two. The NY Times ran a story in December 1907 about the eventual completion of the structure and how it would take over as the world's tallest building, surpassing another then-unfinished building, the Singer Tower. In the era before widely available air travel, the building's vantage point was remarkable.

The view from the top was of a new New York. No other skyscrapers obstructed the vista in either direction. Passing the green roof of the Flatiron Building, the gaze literally spanned the Jersey City Heights and rested on Newark and towns on the Orange Mountains, fifteen miles away.

To the southward the skyscrapers bulked like a range of hills in steel and mortar, the Singer tower rising in the midst, a solitary watch tower on a peak. This hid the harbor, but to the left beyond the bridges, reduced at this height to gray cobwebs, the eye caught the sunlight on the sea -- a long strip of shimmering silver beyond Coney Island and the Rockaways.
